On May 28, 2026, at its "Dare to Act" Intelligent Strategy Launch Event in Shenzhen, BYD officially unveiled a brand-new addition to its Dynasty Series: the 2026 Song Ultra DM-i. Certified by the Ministry of Industry and Information Technology (MIIT) as a standard B-segment plug-in hybrid SUV, this model distinguishes itself through its core strengths of long range, spacious interior, advanced intelligence, and superior safety. It marks the first time a vehicle offering a 310km CLTC pure-electric range has entered the sub-¥130,000 market segment. Furthermore, it features the Dynasty Series' debut of the "DiDiXia" AI Intelligent Agent alongside BYD's fifth-generation DM hybrid technology, creating an all-around solution for families worldwide that seamlessly balances pure-electric urban commuting with anxiety-free long-distance travel.
The 2026 Song Ultra DM-i is available in five distinct configurations, offering two pure-electric range options: 205km and 310km. The official manufacturer's suggested retail prices range from ¥129,900 to ¥159,900, notably bringing the 310km pure-electric range model into the sub-¥130,000 price bracket for the first time:
205KM Leading Edition: ¥129,900
205KM Superior Edition: ¥139,900
310KM Leading Edition: ¥139,900
310KM Superior Edition: ¥149,900
310KM Premium Edition: ¥159,900
Based on the vehicle specifications published in the 405th batch of new vehicle announcements by the MIIT, the Song Ultra DM-i measures 4850mm in length, 1910mm in width, and 1670mm in height, with a wheelbase of 2840mm. Positioned as a standard mid-size (B-segment) SUV, it features a spacious five-seat layout, delivering class-leading performance in terms of interior space. "Large Bed" Mode: Both front and rear seats can be fully reclined to create a completely flat, spacious resting area, catering to the needs of outdoor scenarios such as camping and long-distance layovers.
"Queen's" Front Passenger Seat: Equipped as standard with massage, ventilation, heating, and an electric leg rest, balancing both comfort and a sense of luxury.
Seating Experience: The rear cabin offers ample legroom, making it suitable for a wide range of scenarios, including family outings and business receptions.
The new vehicle features BYD's 5th Generation DM (Dual Mode) plug-in hybrid technology, with power and fuel consumption parameters officially verified by both the manufacturer and China's Ministry of Industry and Information Technology (MIIT):
Powertrain: A 1.5L naturally aspirated engine (max power: 74 kW) paired with a front-mounted drive motor (max power: 175 kW). This system is matched with a FinDreams Blade Battery (Lithium Iron Phosphate chemistry), available in two capacity versions: 26.628 kWh and 38.029 kWh.
Range Performance: Offers a CLTC-rated pure electric range of 205 km or 310 km. With a full tank of fuel and a fully charged battery, the combined maximum range reaches up to 1,845 km, completely eliminating range anxiety.
Fuel Efficiency: Under NEDC conditions with a low battery charge, fuel consumption is as low as 3.3 L/100 km. For daily commuting, the vehicle can operate entirely on electricity; for long-distance travel, the hybrid system ensures highly economical fuel consumption.
The 310 km pure electric version is capable of covering the commuting needs of most users for up to two weeks. For urban mobility, it allows for a true "electricity-only" driving experience, while for long-distance road trips, it leverages the hybrid system to enable extended travel without the need for refueling stops.
The Song Ultra DM-i is the first model in BYD's "Dynasty" series to feature the "DiDiXia" AI Intelligent Agent system. Unlike traditional, passive voice assistants, this system prioritizes the philosophy of "technology actively adapting to the human user":
Proactive Interaction: Based on user habits, the system can proactively offer greetings and content recommendations, fostering a seamless and intuitive rapport between the driver and the vehicle.
Full-Scenario Voice Control: Supports natural language processing, allowing users to execute tasks—such as searching for songs or movies, finding restaurants, or booking tickets—using simple, even vague, verbal commands.
Continuous Evolution: Supports Over-the-Air (OTA) updates; future updates are planned to extend coverage to select existing BYD EV models, ensuring the system remains fresh and up-to-date through continuous improvement. The interior comes standard with a 15.6-inch floating central touchscreen and a 10.25-inch full-LCD instrument cluster, paired with a 16-speaker "Sound of the Sky" audio system to create an immersive, intelligent cabin experience.
The new vehicle features several chassis and safety configurations unique to its class, balancing both handling and protection:
DiSus-C Intelligent Damping Body Control System: Offers millisecond-level damping adjustment for refined vibration filtering, balancing both handling agility and ride comfort;
TBC High-Speed Tire Blowout Stabilization System: Capable of rapidly stabilizing the vehicle body in the event of a tire blowout at speeds up to 140 km/h, thereby significantly reducing the risk of accidents;
Passive Safety: The entire lineup comes standard with 7 airbags (including a far-side airbag) and utilizes a "cage-structure" body design combined with a full-frame subframe for comprehensive protection;
Active Safety: Equipped with features such as Automatic Emergency Braking (AEB), driver fatigue monitoring, and a five-channel dashcam system to provide all-around risk avoidance.
Adhering to the philosophy of "high-spec as standard," the Song Ultra DM-i offers over 100 standard features across its entire lineup, including 43 features that lead its class:
Core Standard Features: 7 airbags, a panoramic glass roof with an electric sunshade, an electric tailgate, 19-inch alloy wheels, power-adjustable seats for both the driver and front passenger, 50W wireless fast charging, a dashcam, and more;
Intelligent Driving Options: Available with the optional "DiLink—Eye of God (Laser Edition)" advanced driver-assistance system, which offers dual-redundancy safeguards for both urban navigation and intelligent parking scenarios, thereby alleviating user concerns regarding the adoption of advanced intelligent driving technologies.
As a flagship B-segment plug-in hybrid SUV launched by BYD for the global family-car market, the 2026 Song Ultra DM-i centers on the core principle of making advanced technology accessible to all. It brings a long pure-electric range of 310 km, advanced intelligent features, class-transcending interior space, and exclusive chassis configurations down to the accessible price point of the 130,000-yuan class. By simultaneously meeting the pure-electric commuting needs of urban users and resolving range anxiety for long-distance travel, it offers global consumers a high-value, all-scenario-capable new energy mobility solution, thereby further solidifying BYD's leading position in the global plug-in hybrid SUV market.
